From the ratio gotten, the total cost of the pepper will be $129.90.
How to solve a ratio
Since the students planted 8 tomato plants and 16 pepper plants in a school garden. The ratio will be:
= 8/16 = 1:2
This year, the students planted 15 tomato plants, the number of pepper will be:
= 15 × 2 = 30
Since pepper plants cost $4.33 each, the total cost will be:
= 30 × $4.33
= $129.90

The required expression is 2x + 5 that equivalent to the expression, 3 + 2x − 9 − 4x + 11 + 5x − x.
What are Equivalent Expressions?The expressions that have identical values are called to be equivalent expressions.
The expression is given in the question following as:
⇒ 3 + 2x − 9 − 4x + 11 + 5x − x
We have to determine the equivalent expression to the given expression
As per the question, we have
⇒ 3 + 2x − 9 − 4x + 11 + 5x − x
Combine the like terms together in the above expression,

A least-squares equation that summarizes this relationship is
Based on the residual plot, is a linear model appropriate for summarizing this relationship?
A linear model is appropriate because the value of r is close to 1.
A linear model is appropriate because the residual plot is curved.
A linear model is not appropriate because the residual plot shows a clear pattern.
A linear model is not appropriate because the scatterplot relating time and subscribers shows a clear pattern.
PLS HURRY
Based on the residual plot, is a linear model is not appropriate for summarizing this relationship. Therefore, the correct answer option is: C. A linear model is not appropriate because the residual plot shows a clear pattern.
What is a residual plot?In Mathematics, a residual plot is sometimes referred to as scatter plot and it can be defined as a type of graph which is used for the graphical representation of the values of two (2) variables, with the resulting points showing any association or correlation (relationship) between the data set.
Mathematically, a linear model can be represented by this mathematical expression; y = mx + b.
Where:
m represents the slope.x and y are the points.c represents the y-intercept.By critically observing the residual plot (scatter plot) which shows a relationship between the residuals and quarters since January 2011, we can reasonably infer and logically deduce that a linear model is not appropriate because there is a clear pattern between the data points.

if you were to guess how probability of tunneling through a finite barrier scales with barrier size (once it's bigger than a wavelength), which would you pick?
As an object's mass and the energy difference between it and the barrier's energy increase, the probability that it will tunnel through the barrier diminishes.
And although while the functionality shows that the wave function never fully hits zero, this explains why tunneling is common at the nanoscale but insignificant at the larger scale. The probability of tunneling declines exponentially with the square root of the mass of the particle (smaller particles may more easily tunnel through barriers than larger ones) and the barrier thickness.
Three requirements must be satisfied for a quantum particle to appreciably tunnel through a barrier ,
The barrier's height must be limited and its thickness should be minimal.The barrier's potential energy (E/V) is greater than the particle's kinetic energy.The fact that the wavefunction can pass through the barrier indicates that the particle possesses wave characteristics. This shows that quantum tunneling does not apply to macroscopic items and only applies to microscopic objects like protons or electrons.To learn more about tunnelling

If m is the centroid of triangle abc, am = 44, ce =54, and dm = 23, find each missing measure. fm=?
If m is the centroid of triangle abc, am = 44, ce =54, and dm = 23, then each missing measure fm=88 and ce=44.
What is the centroid ?The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians intersect. It can alternatively be described as the location where the three medians come together. A line connecting a side's midpoint and the triangle's opposite vertex is called the median.
How do you find the centroid of a triangle with 3 points?Step 1: Identify each vertex's coordinates.
Step 2: Add together and divide by three all the x values from the coordinates of the three vertices.
Step 3: Add together all the y values from the three vertices and divide the result by three.
Step 4: The centroid coordinate is determined from the values collected in stages 2 and 3.
the ratio of both segments is 2:1.
where;
am = 44 and dm = 23
the longer segment is double of shorter one:
2*23 = 46.
Therefore,
fm = 46-23
= <<23=23>>23
now finding ce:
= 2*44
= 88, so

classify the series -1+2+(-4)+8+...as arithmetic or geometric. Then, determine whether the series is convergent or divergent.
Answer:
The series -1+2+(-4)+8+... is an arithmetic series because it has a common difference between consecutive terms. Specifically, the common difference is -4 - 2 = -6.
To determine whether the series is convergent or divergent, we need to find its sum. The sum of an arithmetic series is given by the formula:
sum = (n/2)(a1 + an)
where n is the number of terms in the series, a1 is the first term, and an is the nth term.
Since the series is infinite, we cannot determine its sum using this formula. However, we can determine its sum by taking the limit as n approaches infinity. Using the formula above, we find that the sum is equal to:
sum = (infinity/2)(-1 + infinity)
Since the series contains an infinite number of negative terms, it is divergent.

Hello,
I hope you and your family are doing well!
To find the total area of all four walls of the room, you need to find the area of each wall separately and then add them all together. The area of a wall is the product of its height and width.
The width of each wall is 50 meters, and the height of each wall is 10 meters, so the area of each wall is 50 * 10 = 500 square meters. There are four walls in the room, so the total area of all four walls is 500 * 4 = 2000 square meters.

8n+7=-4n+19
Answer: n= 1
Step-by-step explanation:
8n+7=-4n+19
First, subtract 7 from both sides
8n = 4n +12
Then add 4n from both sides
12n = 12
Then divide by 12 from both sides
n= 1
If you can please give me a Brainliest, thank you!
Answer: n = 1
Step-by-step explanation:
First, you could start off by bringing the -4n to the left side:
8n + 7 = -4n+19 → 12n + 7 = 19
Next, you take the 7 on the left side of the equals sign and subtract it from the 19:
12n + 7 = 19 → 12n = 12
Finally, you divide the 12 on the right by the 12 on the left:
12n = 12 → n = 12/12
A number over itself will always be 1, so n = 1.

Step-by-step explanation:
∠ 1 and ∠ 2 are a linear pair and sum to 180° , that is
x - 6 + 5x = 180
6x - 6 = 180 ( add 6 to both sides )
6x = 186 ( divide both sides by 6 )

By applying the exterior angle of a triangle theorem, m<WUV = 19°
What is an exterior angle of a triangle?
The angle created by one side of a triangle and the subsequently extended side is known as the external angle of a triangle. A triangle has three exterior angles, and the sum of those three external angles is always 360 degrees.
Here, we have
The given parameters are;
ΔUVW with side UW extended to X
m∠UVW = (x + 19)°
m∠VWX = (5x +14)°
m∠WUV = (x + 13)°
Applying the exterior angle of a triangle theorem:
m∠WUV + m∠UVW = m∠VWX
(x + 13)° + (x + 19)° = (5x +14)°
2x + 32 = 5x + 14
32 - 14 = 5x - 2x
18 = 3x
x = 6°
Now, we put the value of x in m∠WUV = (x + 13)° and we get
m∠WUV = (6+13)°
m∠WUV = 19°
Hence, by applying the exterior angle of a triangle theorem, m<WUV = 19°

swhat happens to the diagonal of a rectangle when the rectangle is reflected across a line of symmetry? what does this suggest about the diagonals of rectangles?
When reflected across a line of symmetry, a shape having that line of symmetry will fall on itself. These are the actual claims:
(1) The rectangle's diagonals will line up exactly with one another.
(2) A rectangle's diagonals are symmetry lines.
We deduce from the question that the rectangle is mirrored across the symmetry line.
When done, the rectangle's half will fall directly on the other half.
This indicates that the rectangle's diagonal will line up perfectly with the opposite diagonal.
